Solve this problem 8x + 4(x-1)
a. 32x+3
b. 12x-4
c. 12x+4
d. 9x-4

b

Step-by-step explanation:

8x +4(x -1)

Expand by multiplying 4 into each term inside the bracket:

= 8x +4(x) +4(-1)

= 8x +4x -4

Simplify

= 12x -4

Thus, the answer is b.

8x + 4(x-1)

Let's start of by applying the distributive property

8x + 4x - 4

Next, let's add the variables.

12x - 4

The answer would be option B.

Hope this helps!

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
